Description

Cutting net for cutting grass

Technical Field

The utility model belongs to the technical field of fresh flowers and plants branch and leaf treatment facility technique and specifically relates to cut grass with cutting net.

Background

A straw cutter, also called a leaf cutter, is a device for cutting fresh or semi-dried flowers, grass or branches and leaves (generally fresh medicinal herbs with high value and high cutting requirements). For example, a leaf crusher developed and applied for Chinese patent by me department has a patent number of 201521015965.4, and a novel leaf crusher developed and applied for Chinese patent by me department has a patent number of 201521015963.5.

The high-speed motion of blade or sawtooth (see a novel garrulous leaf machine, see figure 3 of patent No. 201521015963.5) is driven through the motor to the material to current hay cutter, because the material falls by the influence of gravity, so cutting speed must be fast enough just can accomplish the cutting to the material (blade slew velocity usually reaches 1000 revolutions per minute), so prior art has the shortcoming such as blade wearing and tearing height, and the preparation technology requirement of blade is also very high in addition.

Disclosure of Invention

To prior art's not enough, the utility model provides a cut grass and use cutting net for replace the blade of current chaffcutter or garrulous leaf machine.

The technical scheme of the utility model is that:

the cutting net for cutting grass comprises a driving net, a driven net and a shaft mechanism, wherein the driving net and the driven net are round metal sheets provided with a plurality of arc-shaped through holes, a square mounting hole is formed in the center of the driving net, and a round mounting hole is formed in the center of the driven net;

the axle mechanism includes the upper cover, the main shaft, a bearing, the collet, transmission shaft and locking screw, the main shaft from the bottom up is the hexagonal arch in proper order, a pedestal, the axial region, square platform and screw rod, the hexagonal arch inserts the hexagonal groove department at transmission shaft top down, the hexagonal arch corresponds with the transmission shaft and is provided with the screw, locking screw is from transmission shaft bottom screw in and with transmission shaft and main shaft spiro union, the base embedding of main shaft is in the collet, the bearing is established to the axial region periphery cover of main shaft, driven net is established to the bearing overcoat, square platform periphery cover is equipped with the initiative net, screw rod and upper cover spiro union, thereby compress tightly the initiative net, the upper cover still plays the effect of handle except playing the fixed action, thereby the workman of being convenient for grabs and holds the upper cover and mentions whole cutting net.

Furthermore, the arc through holes arranged on the driving net and the driven net are at least in three forms, and the widths of the arc through holes in the three forms are the same, but the lengths of the arc through holes are different.

Further, the arc through-hole that sets up on the initiative net is anticlockwise arrangement, the arc through-hole that sets up on the driven net is clockwise arrangement, and its benefit makes the arc through-hole between them form alternately easily, is fit for producing the shearing action to the material of whereabouts.

In a preferred embodiment, the arc-shaped through hole of the active net is provided with three forms, wherein the first form is an inner short hole surrounding the periphery of the square mounting hole, the second form is a long hole surrounding the periphery of the inner short hole, and the third form is an outer short hole arranged at intervals of two long holes; the arc-shaped through holes of the driven net are provided with three forms, the first form is inner long holes surrounding the periphery of the circular mounting hole, the second form is outer long holes surrounding the periphery of the inner long holes, and the third form is short holes between adjacent outer long holes. The holes between the two nets are staggered as much as possible, so that the crossing is favorably formed, and the shearing action is improved.

In a preferred embodiment, the upper cover is in a hexagonal column shape, which is advantageous in that: the concave surface is not formed, so that the material is not easy to be entangled; the appearance is hexagonal, does benefit to the spanner and twists.

The utility model has the advantages that: the rotating speed difference of the two net surfaces is utilized to form a plurality of cross points, materials are sheared when falling from the cross points, the shearing action can be completed at a low rotating speed, the abrasion of tools is reduced, and the energy consumption of a motor is reduced; in addition, when a hard object is clamped at a cross point between the two net surfaces, the driven net is not fixed and can be driven to rotate by the driving net and the hard object, so that accidents similar to knife breakage of the blade can not be caused, and the safety performance is improved.
